Description

Technical Field

[0001] The utility model belongs to the technical field of battery assembly equipment, and particularly relates to a device for pushing battery cells and a battery cell casing machine. Background Art

[0002] Lithium batteries are widely used in industries such as new energy vehicles and energy storage. Especially in recent years, with people's attention and investment in new energy, new energy vehicles have developed rapidly, driving the rapid improvement of lithium battery technology and increasing the market demand for prismatic batteries in new types of batteries.

[0003] Currently, in the production process of prismatic batteries, it mainly includes processes such as the production of battery cells, inserting battery cells into casings, packaging, and assembling battery packs into battery modules. And in the above production process, inserting battery cells into casings is a very crucial link. The production process of traditional battery cell casing machines mainly includes the following processes: First, the aluminum casing is fed into the aluminum casing positioning port through a feeding mechanism, and the aluminum casing is positioned and shaped at the casing positioning mechanism; then, the battery cells on the battery cell carrier are pushed into the battery cell guiding port and inserted into the aluminum casing through a battery cell pushing mechanism; finally, after the battery cells are inserted into the casings, the batteries formed after inserting the battery cells are removed through a battery handling mechanism.

[0004] However, since the battery cells are generally packaged with Mylar films and the tabs are ultrasonically welded, and then installed in the aluminum or steel casing brackets for welding the top covers. When the gap between the battery cell and the inner wall of the casing is too small, it will not only increase the difficulty of inserting the battery cell into the casing, but also easily lead to problems such as low insertion success rate due to the skew of the top cover during the entire process of inserting the battery cell into the casing, and the problem of lack of protection for the tabs. Summary of the Utility Model

[0005] The technical problem solved by the utility model is to provide a device for pushing battery cells and a battery cell casing machine that can ensure that the top cover of the battery cell always maintains a fixed posture to dock with the aluminum casing port during the process of inserting the battery cell into the casing, so as to overcome the problems of low insertion success rate due to the skew of the top cover and lack of protection for the tabs existing in the existing process of inserting battery cells into casings.

[0006] To solve the above technical problems, on the one hand, the present utility model provides a device for pushing the battery core, which includes a battery core pushing bracket. A sliding bracket is slidably installed at the upper end of the battery core pushing bracket through a linear guide rail. The sliding bracket is equipped with a first linear driving mechanism and a first mounting plate. On the front side of the first mounting plate, a top cover reference block, a first auxiliary bracket, and a second auxiliary bracket are installed. At least two suction cup mounting holes are provided at the front end of the top cover reference block, and top cover vacuum suction cups are installed in the suction cup mounting holes. The first auxiliary bracket and the second auxiliary bracket are oppositely arranged on both sides of the top cover reference block, and a set of rubber-coated rollers and tongues are provided at both ends of the first auxiliary bracket and the middle of the second auxiliary bracket respectively. The three sets of rubber-coated rollers and tongues are arranged in a triangular pattern. When the present utility model is applied to push the battery core to move, on the one hand, the present utility model can suck the top cover through the top cover vacuum suction cups installed in the top cover reference block and make the top cover closely adhere to the top cover reference block. On the other hand, the present utility model can limit and protect the ear and the top cover through the tongues, and limit and fix the battery core body through the three-jaw rubber-coated rollers, so as to ensure that the top cover is butted against the aluminum shell opening in a proper posture, avoid damaging the battery core and the ear, and thus greatly improve the smoothness of the battery core entering the shell and reduce the risk of failure of the battery core entering the shell.

[0007] Further, the tongue includes a mounting block. One end of the mounting block is installed on the first auxiliary bracket or the second auxiliary bracket through a fastener. The other end of the mounting block is provided with a sliding groove. One end of the sliding groove is provided with a cover plate, and the other end of the sliding groove is slidably installed with a tongue body. A spring is provided between one end of the tongue body close to the cover plate and the cover plate. In this way, it can not only ensure that the top cover maintains a fixed posture, but also prevent the ear from being damaged during the material pushing process.

[0008] Further, the first linear driving mechanism includes a battery core pushing cylinder. The cylinder body of the battery core pushing cylinder is fixedly connected to the sliding bracket, and the end of the piston rod of the battery core pushing cylinder is fixedly connected to the battery core pushing bracket. The extension or retraction of the piston rod in the battery core pushing cylinder is used to control the sliding bracket and the components installed on the sliding bracket to move in the corresponding direction.

[0009] Further, a first fixing plate is further provided at the upper end of the battery core pushing bracket. A pressure sensor is provided on the side of the first fixing plate facing the sliding bracket. The contact of the pressure sensor can contact the sliding bracket, so that it can detect and feedback the pressure borne by the sliding bracket in real time during the process of the battery core entering the shell, so as to reduce the material loss caused by abnormal pressure.

[0010] On the other hand, the present utility model also provides a battery core entering shell machine, which includes a frame. Along the length direction of the frame, a device for taking the battery core after entering the shell, an aluminum shell centering device, an opening and closing device, a battery core centering device, and the above-mentioned battery core pushing device are sequentially arranged.

[0011] Further, the opening and closing device includes a mounting base plate installed on the frame. On one side of the mounting base plate facing the battery cell centering device, an upper limit guiding mechanism and a lower limit guiding mechanism with the same structure are symmetrically arranged. A left limit block and a right limit block are arranged between the upper limit guiding mechanism and the lower limit guiding mechanism. The battery cell and the aluminum shell are limited and guided by the upper limit guiding mechanism and the lower limit guiding mechanism, so as to avoid scratching between the battery cell and the shell opening during the process of the battery cell entering the shell, and ensure the success rate of the battery cell entering the shell.

[0012] Further, a shell opening pulling mechanism is installed on one side of the mounting base plate close to the aluminum shell centering device. The shell opening pulling mechanism includes a pulling cylinder installed on the mounting base plate through a fastener. The output end of the pulling cylinder is connected with a mounting plate three through a floating joint. Guide rods are installed at both ends of the mounting plate three. The guide rods are slidably connected with a fixed plate two installed on the mounting base plate through linear bearings. And the end of the guide rod passes through the fixed plate two and is sequentially sleeved with a spring and a limit block. A gas distribution block is installed in the middle of the mounting plate three, and shell opening vacuum suction cups are arranged at each air port of the gas distribution block. In this way, the present utility model can first control the pulling cylinder to press down until the shell opening vacuum suction cup sucks the shell opening, and then control the pulling cylinder to cut off the air supply and be in a free state. At this time, it can rely on the elastic force of the compressed spring to pull the shell opening to slightly open the shell opening, so as to assist the battery cell to enter the shell, reduce scratching, and improve the qualification rate of the battery cell entering the shell.

[0013] Further, the structures of the aluminum shell centering device and the battery cell centering device are the same.

[0014] Further, the battery cell centering device includes a reference mounting seat and a pushing and tightening mounting seat installed on the frame. A reference positioning cylinder is installed at the upper end of the reference mounting seat, and a reference positioning plate is installed at the output end of the reference positioning cylinder. A pushing and tightening cylinder is installed at the upper end of the pushing and tightening mounting seat, and a pushing and tightening positioning plate is installed at the output end of the pushing and tightening cylinder. The pushing and tightening positioning plate is arranged opposite to the reference positioning plate, and the pushing and tightening positioning plate and the reference positioning plate can approach or move away from each other to realize the corresponding battery cell centering operation. In addition, as a preference, in the present utility model, the cylinder diameter of the reference positioning cylinder is larger than that of the pushing and tightening cylinder, and the positions on the pushing and tightening positioning plate and the reference positioning plate for contacting the battery cell are preferably made of POM material to avoid damaging the battery cell; PEEK strips are inlaid at the positions on the reference mounting seat and the pushing and tightening mounting seat for supporting and placing the battery cell, so that it can not only reduce the high cost brought by using rubber-coated bearings, but also ensure that there are no scratches on the battery cell during the sliding friction process.

[0015] Further, the device for picking up the battery cell after it is put into the shell includes a picking-up bracket. The lower end of the picking-up bracket is slidably mounted on the frame through two groups of horizontal linear modules. The upper end of the picking-up bracket is provided with a picking-up gripper, and the position on the picking-up gripper that comes into contact with the battery cell preferably uses polyurethane material to avoid scratching the surface of the battery cell. The horizontal linear module preferably uses a double-slider single-acting linear module on the market to simplify the overall structure and facilitate subsequent installation and debugging.

[0016] As can be seen from the above technical solutions, the present utility model has the following advantages: When applying the present utility model to push the battery cell to move and realize the action of putting the battery cell into the shell, on the one hand, the present utility model can suck the top cover through the top cover vacuum suction cup installed in the top cover reference block and make the top cover closely adhere to the top cover reference block; on the other hand, the present utility model can limit and protect the pole ear and the top cover through the insertion tongue, and limit and fix the battery cell body through the three-claw rubber-coated roller, so as to ensure that the top cover docks with the aluminum shell opening in a correct posture, avoid pressing the battery cell and damaging the pole ear, and thus greatly improve the smoothness when the battery cell is put into the shell and reduce the risk of failure of putting the battery cell into the shell.
